Gorillaz have shared their new song 'Friday the 13th' featuring French-British rapper Octavian, marking the fourth episode of their ongoing Song Machine series.

The slow burner track features vocals over a psychedelic beat, with the London-based artist singing of sleepy, drug-induced confusion.

"I call my dealer, said, 'Share the white with all of us'/ I told him, 'We've been so nice, don't turn on us'/ It's funny how time flies by so fast?"

Member 2-D adds his own hazy refrain, "If I look into your eyes, I can realise."

The animated clip for the track superimposes Octavian's image as a negative over a hallucinatory highway scene, reimagining a blurry comedown after a lengthy night out.

The song comes after the release of three previous Song Machine songs from the Damon Albarn-led animated group; 'Aries' (featuring Peter Hook and Georgia), 'Désolé' (featuring Fatoumata Diawara) and 'Momentary Bliss' (featuring Slowthai and Slaves).

The group announced their first ever comic book, Gorillaz Almanac, in May. The comic will be in partnership with Z2 Comics to celebrate their 20-year history, and is set for an October release.
